There has been some question about McGary's height. He's been consistently listed at 6'10", but a newspaper article recently listed him at 6'8". UMHoops reports that he measured 6'9" w/out shoes at the Nike Hoops Summit.
McGary weighed 263 at the Hoops Summit, which UMHoops says is too much. Sam Webb said that he was a bit overweight this morning as well.
I've watched a lot of his film now, and I can offer the following non-expert thoughts:
1. He's an excellent ballhandler for a man his size. He's also a willing passer;
2. He's a good enough athlete but not at all elite;
3. He plays with a very high, Novak-like motor. This wasn't on display at the Hoop Summit, apparently, but he reportedly seemed to be banged up (see link above);
4. His shooting is inconsistent at best. He can make threes, but he throws up ugly line drives fairly often as well (including on free throws);
5. I don't think he's going to be a big-time shot blocker in college. He gets a good amount of blocks in his highlights against shorter guys (I'm talking short-for-high-school guys), but you don't see the sort of timing and extension that you'd see from, say, Gorgui Dieng;
6. I can see him being particularly successful on the pick-and-roll, b/c he'll be able to receive the ball a dribble or two away from the rim and still convert, which is something Jordan Morgan struggles with;
7. McGary is raw and a little wild at times with the basketball. His choice to be coached by John Beilein was particularly wise, IMO, b/c Beilein will work more on his shooting skills than other coaches. Bacari Alexander will also presumably be a great help to him. McGary won't be the best player on the team next year, but he'll be a very nice (if unrefined) piece to the puzzle.
